The mine flameproof permanent magnet synchronous frequency conversion motor is a low-speed and high-torque direct-drive motor, which can drive various general machinery such as belt conveyors and hoists without a reducer. It is widely used in mining, building materials, electric power, steel, pharmaceutical, non-ferrous metals and other key industries to drive various general machinery, such as belt conveyors, mills, elevators, separators, mixers, fans, pumps, cutting machines and other mechanical equipment. The permanent magnet synchronous frequency conversion motor adopts the double insulation process of "VPI vacuum pressure impregnation + epoxy resin vacuum potting", which has high insulation reliability.

High efficiency and energy saving
the motor efficiency reaches the first-class energy consumption (IE5) standard, eliminating the intermediate transmission devices such as reducer and mechanical soft lifting, and the system efficiency is increased by 10%-25%; The load factor is in the range of 25%~120%, and the motor can ensure high efficiency.
Large starting torque and strong overload capacity
the starting torque is up to 2.2 times the rated torque, and the overload torque is up to 2 times the rated torque.
High product reliability
frequency conversion start, small starting current, reducing the impact of large current on the power grid and torque fluctuation on the mechanical impact of the equipment.
Low maintenance
every 3000 hours of operation, only one bearing lubrication is required, eliminating the maintenance of intermediate transmission devices such as reducer and mechanical soft lift, and the maintenance amount is reduced by more than 80%.
Lower noise
Because the permanent magnet variable frequency direct drive system does not have the meshing of gears, the noise is lower, and the three-phase permanent magnet synchronous variable frequency motor runs under low speed and high torque, so there is no vibration caused by high-speed rotation unbalance, and the noise is lower.
